motor life is ensured with the use of external resistor banks or liquid rheostats that dissipate heat buildup generated during motor startup. What makes the wound rotor motor a unique induction machine is its rotor. Instead of a series of rotor bars, a set of insulated rotor coils is used to accept external impedances.

A soft starter is an electronic device which regulates the voltage flowing to the motor at startup. By slowly ramping up the supply voltage to the motor, a smooth start without excessive current flow can be achieved. Soft starters are more expensive than DOL or stardelta, but they are widely used due to their convenience and simplicity.
